Abstract

La présente invention concerne un module à machine électrique incluant une machine électrique avec un bloc stator. Le bloc stator comprend une pluralité de disques en tôle d'induit de stator couplés entre eux et une pluralité de conducteurs positionnés à travers des fentes axiales de la pluralité de disques en tôle d'induit de stator. Le module à machine électrique comprend également un canal à réfrigérant au moins partiellement défini à l'intérieur des fentes axiales et un boîtier. Le boîtier entoure au moins partiellement la machine électrique et définit au moins partiellement une cavité de machine qui est en communication fluidique avec le canal à réfrigérant.
